This research aimed to assess the impact of applying mountain microorganisms (MM) on coffee seedling production. Two nurseries (A and B) were used with weekly and bi-weekly treatment applications. Plant height, leaf and root lengths, and dry matter content (DM) were measured. Results showed that Nursery A, with weekly treatments, exhibited greater height and leaf length growth compared to Nursery B. In the initial measurement, Nursery A accumulated more leaf DM than Nursery B. However, over time, both nurseries experienced a decline in DM. Root length variability was observed in both nurseries throughout the measurements. Treatments with MM from forest and coffee systems in Nursery A showed higher leaf DM accumulation in the initial measurement. In conclusion, MM application, especially with higher frequency, promoted coffee seedling growth. The results emphasize the need for detailed analysis to understand optimal root development conditions. The decline in DM over time is a natural response to active growth, indicating increased nutritional requirements. These findings support MM-based strategies for sustainable coffee seedling production.
